Bypassing stupid survey sites?

Is there any way of bypassing these sites? They ask for a mobile phone number and I tried using a proxy (US proxy) so that the site could see me as US resident and I also have a pinger.com free mobile number. No luck, I see myself in a loop of surveys...
I couldn't find a working UK proxy to text some fake mobile numbers I have here...

Good luck with this. IIRC, some members have offered apps that do this, and there are a number of Youtube postings showing how to do this. But I have failed to discover any working solution. I seriously doubt these sites actually have what they claim. "survey" is "sucker" misspelled.
